OSH, Kyrgyzstan – Heavy arms fire rang out over the Kyrgyz city of Osh before dawn Wednesday as authorities struggled to bring order to the Central Asian country's south after days of deadly ethnic riots. The violence — which erupted last Thursday in Osh between the majority Kyrgyz population and Uzbeks and spread to surrounding regions — has prompted more than 100,000 Uzbeks to flee for their lives to Uzbekistan, with tens of thousands more camped on the Kyrgyz side of the border or stranded in a no man's land. Humanitarian aid was trickling in via Uzbekistan, though some supplies coming via Osh were reportedly intercepted and volunteers attacked. One of the few Uzbek families to remain in Osh told the Associated Press that a mother of two was killed by shrapnel from a shell launched toward their home by the Kyrgyz military. "The Kyrgyz are out of control. They are destroying us," said Abdumanap Mamasydykov, 38, at a funeral for the woman, his 48-year-old sister Gelbar Alynbayeba. They had remained in Dostyk, an Uzbek quarter of Osh, to tend to elderly relatives too frail to flee. The claim that authorities were firing on Uzbeks could not be verified, but an AP photographer saw military patrols and heard artillery fire from their positions in central Osh overnight. No other armed units or groups had been seen. The official death count from the past week of violence rose to 189 on Wednesday, with 1,910 wounded, the Health Ministry said. But observers believe the real toll is much higher, with many victims being buried quickly in keeping with Muslim tradition. Meanwhile, thousands of ethnic Uzbeks were camped in squalid condition near the Uzbekistan border, waiting to cross and enter one of the dozens of refugee camps there. At a crossing near Jalal-Abad, frustration was mounting as several hundred who had made it into Uzbekistan tried to return to Kyrgyzstan but were refused re-entry.
